Abstract
The utility model discloses a kind of motor shaft operator guards, comprise drill point, protective cover, bearing block, screw, motor, gauge tap, clutch shaft bearing, overstriking reducing bearing axle, the second bearing, shell, handle and power line; Described drill point is arranged in protective cover, and drill point is connected with the overstriking reducing bearing axle be inserted in clutch shaft bearing; Clutch shaft bearing and the second bearing are installed in bearing block; Described motor is arranged in the enclosure, and the rotating shaft of motor is inserted in overstriking reducing bearing axle; Overstriking reducing bearing axle and drill point adopt stationary fit frock technique, and ensure that the concentricity of axle and load remains unchanged, bearing drag coefficient also can not change, and also ensure that output power of motor; Electric motor main shaft and load thickened shaft punching tight fit, this is improved axiality again; Revolutionize the shaft distortion caused because diameter is meticulous in the work of Miniature electric drill side direction, the situation bending and then scrap.
Description
Technical field
The utility model relates to motor shaft application, particularly relates to a kind of motor shaft operator guards.
Background technology
The motor that prior art uses, especially motor uses drill bit aspect, is difficult to the g-load ability ensureing to improve machine shaft; The concentricity of axle and load is difficult to guarantee and stablizes constant, and bearing drag coefficient generally can change, and output power of motor is unstable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of motor shaft operator guards.
The utility model is achieved through the following technical solutions:
A kind of motor shaft operator guards, at least comprises drill point, protective cover, bearing block, screw, motor, gauge tap, clutch shaft bearing, overstriking reducing bearing axle, the second bearing, shell, handle and power line; Described drill point is arranged in protective cover, and drill point is connected with the overstriking reducing bearing axle be inserted in clutch shaft bearing; Clutch shaft bearing and the second bearing are installed in bearing block; Described motor is arranged in the enclosure, and the rotating shaft of motor is inserted in overstriking reducing bearing axle.
As further technical scheme of the present utility model: described bearing block is fixedly connected with motor front-end case by screw; Handle is arranged on outer casing back.
Further, described power line is connected with the gauge tap be arranged on shell, gauge tap and connecting terminal of motor wired in series.
As prioritization scheme of the present utility model: described drill point is connected with overstriking reducing bearing axle is concentric, the rotating shaft of motor is inserted in overstriking reducing bearing axle with one heart, and is fixedly connected with by pin.
Compared with prior art, the beneficial effects of the utility model are: this motor shaft operator guards, and overstriking reducing bearing axle and drill point adopt stationary fit frock technique, ensure that the concentricity of axle and load remains unchanged, bearing drag coefficient also can not change, and also ensure that output power of motor; Electric motor main shaft and load thickened shaft punching tight fit, this is improved axiality again; Revolutionize the shaft distortion caused because diameter is meticulous in the work of Miniature electric drill side direction, the situation bending and then scrap; Overall structure is simple, practical, is easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: 1, drill point, 2, protective cover, 3, bearing block, 4, screw, 5, motor, 6, gauge tap, 7, clutch shaft bearing, 8, overstriking reducing bearing axle, the 9, second bearing, 10, shell, 11, handle, 12, power line.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of motor shaft operator guards, at least comprise drill point 1, protective cover 2, bearing block 3, screw 4, motor 5, gauge tap 6, clutch shaft bearing 7, overstriking reducing bearing axle 8, second bearing 9, shell 10, handle 11 and power line 12; Described drill point 1 is arranged in protective cover 2, and drill point 1 is connected with the overstriking reducing bearing axle 8 be inserted in clutch shaft bearing 7; Clutch shaft bearing 7 and the second bearing 9 are installed in bearing block 3; Described motor 5 is arranged in shell 10, and the rotating shaft of motor 5 is inserted in overstriking reducing bearing axle 8.
As further technical scheme of the present utility model: described bearing block 3 is fixedly connected with motor 5 front-end case by screw 4; Handle 11 is arranged on shell 10 rear end.
Further, described power line 12 is connected with the gauge tap 6 be arranged on shell 10, gauge tap 6 and motor 5 binding post wired in series.
As prioritization scheme of the present utility model: described drill point 1 is connected with overstriking reducing bearing axle 8 is concentric, the rotating shaft of motor 5 is inserted in overstriking reducing bearing axle with one heart, and is fixedly connected with by pin.
The utility model is in use: be arranged on by drill bit in drill point, turn on the power switch, and motor starts to rotate, moment of torsion is passed through motor shaft and connects the overstriking reducing bearing axle of motor shaft and drill point by motor, and then power transmission is to drill point, drill point rotates, and drives bit operation
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
